Single nucleotide polymorphic sites in 79 protein-coding genes fromsevenPanax species. The inner track shows the 79 chloroplast CDS genes. Track A represents the total SNPs in all seven Panax species. Track B–G represents SNPs in P. trifolius, P. stipuleanatus, P. vietnamensis, P. japonicus, P. notoginseng, and P. quinquefolius compared to P. ginseng. The red, green, blue, and black lines on each track indicate the four kinds of SNPs (T, A, C, and G nucleotides), respectively. Yellow lines indicate InDel regions.

CDS, coding sequence; InDel, insertions or deletion; SNP, single nucleotide polymorphism.
